Nanotechnology is challenging our traditional metrological techniques for measuring the purity of a compound, but the National Institute of Standards and Technology (NIST) thinks they have an answer. Look for NIST's new metrological regime to be widely adopted among semiconductor researchers and manufacturers. R. Colin Johnson, Kyoto Prize Fellow @NextGenLog

Here is what my story in EETimes says about MEMS resonators: Using a new twist on the traditional thermogravimetric analysis (TGA) technique, the National Institute of Standards and Technology (NIST) demonstrated a new method for taking Nanoscale measurements of the purity of carbon-nanotubes, coated-nanoparticles and surface features on thin films. NIST demonstrated its new TGA microbalance built atop a vibrating quartz crystal, thereby enabling measurements almost 1000-times more sensitive than today...Full Text: http://bit.ly/NextGenLog-gEYS

Lastest Book:

Cognitive computers—cognizers—aim to instill human-like intelligence into our smartphones, tablets and other electronic devices using microchips that emulate the human brain. Dubbed the “Future of Computing” by the NYTimes, one of the “Best Innovation Moments of 2011” by the Washington Post and one of “10 World Changing Ideas” in a Scientific American cover story “A Computer Chip that Thinks” this book reveals how neuroscience and computer science are merging in a new era of intelligent machines light-years beyond Apple's Siri, IBM's Watson.
